Character Bio

Professor Membrane photo
Professor Membrane is the father of Dib and Gaz, but he has very little time for his offspring, being one of the most famous and important people on Earth. The Professor, as he is often called, is rarely at home, so he supervises his kids in the form of a floating monitor, which often spews out pre-recorded reminders that are often way out-of-date. Dib and Gaz refer to him as "Dad".

Although his parenting skills seem to be missing in action, he really does love his kids, making time once a year for dinner together and always remembering to activate the food monitor. However, Membrane is somewhat ashamed of his son's belief in the paranormal, refusing to call it a "proper" science. He believes Dib's obsession is just a phase, or "temporary insanity", that Dib will grow out of, and allows his son to do as he pleases, to an extent. On occasion, Membrane is so preoccupied with work that he fails to recognize his own kids.

Membrane seems to have incredible power, similar to that of Dib's power, when he blasts open the back door with a laser fired from his glove. Professor Membrane also has a never-ending quest to destroy Santa Claus, because instead of giving him twelve cases of Uranium-238 as a child, Santa gave him a box with an infinite number of socks inside.

He has a science TV show similar to which requires the people in the audience to pass several tests just to sit and watch. He is somewhat of a celebrity, and is described as someone "without whom the whole world falls into chaos."

Had the series continued, it would have been revealed that Dib and Gaz are not actually Membrane's birth children. Rather, they were created by the Professor, perhaps as experiments. This may explain why Dib and Gaz seem to have superhuman powers, as well as explaining why they do not seem to have a mother. Dib recalls "I have faint memories of being aboard an alien ship as a baby. I don't know, but I think they were doing tests on me." which may have been him created in Membrane Labs. It is unknown how Membrane created his children however, if they truly are experiments, as Bad, Bad Rubber Piggy reveals that they develop much like normal kids. The Professor looks/is about 40 or so; his first name is unknown, but it is implied that Dib and Gaz do not seem to share the last name of "Membrane." He is also the inventor of "Super toast", although it is not entirely clear how super toast differs from normal toast other than the fact that it increases the size of one's head. His first line in the series was "shhhh... not now, son, I'm making TOAST!"
